WQ_NON_REENTRANT doesn't guarantee ordered execution but it guarantees

work which is executing for long time. In the long run, if using non
reentrant is safe for mac80211, using it would be much better.
No, I don't think it's safe for mac80211.
So maybe my patch is a good enough way to fix this?
Thanks,
